python作图——线型图 饼形图

线性二维图

import numpy as npimport matplotlib.pyplot as pltplt.figure()x=np.linspace(0,2*np.pi,50)y=np.sin(x)plt.plot(x,y,'bp--')#蓝色带星虚线plt.show()

饼型图

import matplotlib.pyplot as pltlabel = ['Frogs', 'Hogs', 'Dogs', 'Logs']sizes= [15,30,45,10]explode=(0,0.1,0,0)colors=['yellowgreen','gold','lightskyblue','lightcoral']#coral珊瑚plt.pie(sizes,labels=label,explode=explode,colors=colors, autopct='%1.2f%%',shadow=True,startangle=90)plt.axis=('equal')plt.legend()plt.show()
